Add the Device Tree binding for the PCIe/USB 3.0 combo PHY found in the SpacemiT K1 SoC. This is one of three PCIe PHYs, and is unusual in that only the combo PHY can perform a calibration step needed to determine settings used by the other two PCIe PHYs. Calibration must be done with the combo PHY in PCIe mode, and to allow this to occur independent of the eventual use for the PHY (PCIe or USB) some PCIe-related properties must be supplied: clocks; resets; and a syscon phandle.

Add the Device Tree binding for two PCIe PHYs present on the SpacemiT K1 SoC. These PHYs are dependent on a separate combo PHY, which determines at probe time the calibration values used by the PCIe-only PHYs.

Add the Device Tree binding for the PCIe root complex found on the SpacemiT K1 SoC. This device is derived from the Synopsys Designware PCIe IP. It supports up to three PCIe ports operating at PCIe gen 2 link speeds (5 GT/sec). One of the ports uses a combo PHY, which is typically used to support a USB 3 port.

Introduce a driver that supports three PHYs found on the SpacemiT K1 SoC. The first PHY is a combo PHY that can be configured for use for either USB 3 or PCIe. The other two PHYs support PCIe only. All three PHYs must be programmed with an 8 bit receiver termination value, which must be determined dynamically; only the combo PHY is able to determine this value. The combo PHY performs a special calibration step at probe time to discover this, and that value is used to program each PHY that operates in PCIe mode. The combo PHY must therefore be probed--first--if either of the PCIe-only PHYs will be used. During normal operation, the USB or PCIe driver using the PHY must ensure clocks and resets are set up properly. However clocks are enabled and resets are de-asserted temporarily by this driver to perform the calibration step on the combo PHY.

Introduce a driver for the PCIe root complex found in the SpacemiT K1 SoC. The hardware is derived from the Synopsys DesignWare PCIe IP. The driver supports three PCIe ports that operate at PCIe v2 transfer rates (5 GT/sec). The first port uses a combo PHY, which may be configured for use for USB 3 instead.

Define PCIe and PHY-related Device Tree nodes for the SpacemiT K1 SoC. Enable the combo PHY and the two PCIe-only PHYs on the Banana Pi BPI-F3 board. The combo PHY is used for USB on this board, and that will be enabled when USB 3 support is accepted.
